FIG. 3 is a diagram showing an example of changing the drawing condition. Examples of data when the drawing condition of the data (a) before the change is changed are shown in (b) to (d2). An example of data with a changed density is (b), an example of data with a changed line width is (c), and an example of data with a changed bit pattern is (d).
1) and (d2). In the above example, the darkness is thin and the line width is thick, but conversely, the darkness may be thick and the line width may be thin. Further, the visual distinction can be presented by changing the drawing conditions other than the above.

Next, the flow of processing in the above embodiment will be described with reference to FIG.

First, when the user gives an instruction to start inputting, the activation process (step S1) activates the handwriting data input device and shifts the screen to the input state. Next, the input area image acquisition processing (step S2) acquires the input area image, and the input area image storage processing (step S3) stores the input area image. Further, input area image change processing (step S4)
Changes the drawing condition of the input area image, and the input area image display process (step S5) displays the input area image whose drawing condition is changed by the input area image changing process (step S4).

Next, the coordinate acquisition process (step S6) takes in the coordinate information of the data written by the user. When the handwriting data input device is set to the input mode, the handwriting saving process (step S7) receives the coordinate information and saves and manages it as handwriting information, and the handwriting changing process (step S8) changes the drawing condition of the handwriting. The handwriting display process (step S9) displays the handwriting whose drawing conditions have been changed on the screen. If the handwriting data input device is set to the edit mode, the handwriting editing process (step S1
0) receives the coordinate information as editing instruction information, and edits the handwriting information stored and managed in the handwriting storage processing (step S7). When the user gives an instruction to end the input, the end processing (step S11) takes in the handwriting saved in the handwriting saving processing (step S7) into the input area image saved in the input area image saving processing (step S3). The image is displayed and the handwriting data input device is terminated.

Next, an operation example in this embodiment will be specifically described. <Operation Example 1> When the user depresses the input start button 11 shown in FIG. 7A to activate the handwriting data input device, as shown in FIG. 7B, the activation process (step S1) is performed with buttons. 21 is displayed, and the input area image display processing (step S5) displays the input area image in which the bit pattern is a dotted line in the input area image changing processing (step S4).
When the user sets the handwriting data input device to the input mode and writes the handwriting, the handwriting display processing (step S9) displays the handwriting 22.

When the user presses the input end button 21a, as shown in FIG. 7 (c), the end process (step S1)
The newly input and edited handwriting 31 stored in 1) in the handwriting storage processing (step S7) is captured in the input area image stored in the input area image storage processing (step S3) and displayed again.

By the above operation, the handwriting written by the input person is shown by a solid line and the input area image is shown by a dotted line so that the handwriting and the input image area can be visually distinguished and can be input or edited in the current input state. The distinction between handwriting and handwriting that is not the target of input or editing becomes clear.

In the above example, the input area image changing process (step S4) changes the bit pattern of the input area image to clarify the distinction between the input area image and the handwriting. Alternatively, the density, the line width, or the like may be changed to clarify the distinction between the input area image and the handwriting. <Operation Example 2> When the user depresses the input start button 11 shown in FIG. 8A to activate the handwriting data input device, as shown in FIG. 8B, the activation process (step S1) includes buttons. 21 is displayed. When the user sets the handwriting data input device to the input mode and writes a handwriting, the handwriting with the line width changed by the handwriting changing process (step S8) is displayed as the handwriting 22 by the handwriting display process (step S9).

When the user presses the input end button 21a, as shown in FIG. 8C, the end process (step S1)
The newly input and edited handwriting 31 stored in 1) in the handwriting storage processing (step S7) is captured in the input area image stored in the input area image storage processing (step S3) and displayed again.

By the above operation, the handwriting written by the input person is made thick and the input area image is made thin so that the handwriting and the input area image can be visually distinguished, and can be input or edited in the current input state. The distinction between handwriting and handwriting that is not the target of input or editing becomes clear.

In the above example, the handwriting change process (step S
8) changed the line width of the handwriting to clarify the distinction between the input area image and the handwriting. However, in addition to the line width, the color, darkness, or bit pattern is changed to change the input area image and the handwriting. The distinction between and can also be made clear. <Operation Example 3> When the user presses the input start button 11 shown in FIG. 9 (a) to start the handwriting data input device, as shown in FIG. 9 (b), the starting process (step S1) includes buttons. 21 is displayed, and the input area image display processing (step S5) displays the input area image in which the bit pattern is a dotted line in the input area image changing processing (step S4).
When the user sets the handwriting data input device to the input mode and writes the handwriting, the handwriting whose line width has been changed by the handwriting changing process (step S8) is displayed as the handwriting display process (step S8).
9) is displayed as handwriting 22.

When the user presses the input end button 21a, as shown in FIG. 9C, the end process (step S1
The newly input and edited handwriting 31 stored in 1) in the handwriting storage processing (step S7) is captured in the input area image stored in the input area image storage processing (step S3) and displayed again.

By the above operation, the handwriting written by the input person is made into a thick solid line and the input area image is made into a thin dotted line so that the handwriting and the input image area can be visually distinguished, and the input and editing in the current input state can be performed. The distinction between the target handwriting and the handwriting that is not input or edited becomes clear.

Also in the above example, the input area image changing process (step S4) changes the color, the density, the line width, etc. in addition to the bit pattern of the input area image, and the handwriting changing process (step S8). It is also possible to clarify the distinction between the input area image and the handwriting by using, in addition to the line width of the handwriting, changing the color, the darkness, the bit pattern, or the like.

As described above, the processing control device 3 acquires an input area image when the apparatus is activated, saves the acquired input area image, and changes drawing conditions when displaying the acquired input area image, Or, change the drawing conditions when displaying the handwriting input by the user after starting this device, or change both of them, and redisplay the saved input area image and the saved handwriting at the end of input. With this configuration, it is possible to clearly distinguish between the handwriting that is the target of input and editing in the current input state and the handwriting that is not the target of input and editing, so that the user can input and edit the handwriting accurately. You can

In the above embodiment, an example in which one of the drawing conditions of the bit pattern, line width, color, density, etc. is changed has been described, but the present invention is not limited to this. Alternatively, a plurality of types such as color and density may be combined and changed.

In the above embodiment, the bit pattern, the line width, the color, and the darkness are used as the drawing conditions by way of example, but the drawing conditions are not limited to these, and the characters can be visually distinguished such as inverted characters and underlines. Other drawing conditions may be used as long as they are.

Needless to say, the input referred to in the claims of the present invention includes not only the input of data but also the input in editing, as shown in the above embodiment.

In the above embodiment, the drawing condition setting means changes the drawing condition of the handwriting previously input by the input area image changing unit 7, and the handwriting changing unit 10 changes the drawing condition of the handwriting input this time. However, instead of this, it may be configured to have only one of them.
